The YouTube video, posted by an Abbotsford, B.C. man named Dwayne Stewart, appears to have been shot through an airplane window and shows handlers flinging small carry-on sized bags.

Stewart also posted the video to his Facebook page, writing, “@aircanada #fail. I'll get this on you tube when I get home. Ever wonder what happens to your bags when you leave them at the aircraft door? #hopeyourcomputerisnotinthere.”

Air Canada responded to complaints on Twitter, saying, “We are extremely disappointed by the actions depicted in this video. An investigation into this has been launched.” The airline also released a statement to the same effect.

A Twitter user by the name Darren, handle @drvanslyke, wrote, “Wow. Just witnessed @AirCanada bag handlers throwing excess carry-ons from top of 777 bridge to hose storage below. At least 20' down.”

The airline responded to his tweet asking for the flight number and pledging to “investigate this matter in-depth.”

Air Canada has come under fire in the past, most recently in April, when it apologized after a famed violinist with a disability was abandoned by the airline at Pearson International airport.
